Celestron CGX Mount Unboxing First Thoughts

Two giant boxes with Celestron written arrived at my doorstep today! I love those days. But today especially as I'd just sold and packed away my trusty EQ6 ready for a newer mount with a bigger max payload capacity. Here are my immediate thoughts on unboxing.

(Disclaimer, I'm on "Team Celestron" so am an ambassador of sorts for them, and I work as a third party with Bintel. However neither of these companies pay me for comment and I pay for my own gear like anyone, though I do get discounts and heads up on new stuff from time to time.)

I won't get the weather or the time to fully test the mount until after xmas, so these are just some observations until I can do some real world testing for you.

- Great build quality, not wobbly and plasticky like some of their past mounts that put me off Celestron mounts initially. Everything is machined and tight, like what you'd expect from an Apple product in a way.

- Like all good reviewers, I threw the manual over my shoulder in disgust and just started mashing things together like lego ... and it worked mostly! The upper axis comes boxed "upside down" but it immediately corrected itself by initialising the "switch positions" when I turned it on.

- I was confused about the azimuth adjustments initially before realising you had to loosen 4 nuts on the base plate before the rotation of the screws would do anything. This was counterintuitive but makes sense as it can be locked down well once polar alignment fine adjustments are made.

- The little windows and removable motor shields are totally useless (for someone like me anyway) but they look great and it's nice to see the belts working away.

- The slew noise is loudish but pretty/unintrusive/smooth/dull .. no variation or squawking that EQ6s sometimes have. Just a clear mechanical whirr. Not too loud, just not quiet.

- The sidereal tracking noise is very quiet indeed. Imperceptible almost like Celestron mounts often are, unlike the EQ6 which has that techno beat buzz you get used to but isn't really that bad anyway.

- The mount remembers your site details / time & date internally which is great, but no amazing feat. All mounts should always have done this in the first place.

- Still no power supply provided with the mount. I don't get it. It's possibly the cheapest thing they could provide aside from the bubble wrap. Not just celestron but all astro vendors - is it too much to ask to include the cable that makes your purchase actually turn on?

- The cable they do provide is the old ciggy-lighter number. I know when the original James Bond drove cars it might have seemed cool, convenient even, to have a power source in your car that also lights your cancer-sticks but why on earth this become the de facto standard for astro gear is beyond me. I kind of like it when Apple kills off floppy drives, USB2 ports and other old standards but astro vendors seem unwilling to do this. I'm ranting beyond the scope of this review, but you know what I mean. These are space age devices, surely we can handle an upgrade to portable power ports by now or you know, include a power supply.

- Double handles, huge knobs all great, but the nuts on the base and for azimuth locking require a large allen key, which though provided, is easily lost and an odd design choice. Makes no difference for me in an observatory but I can see people in the backyard or star parties trying to tighten these flush nuts by hand, scrabbling in the darkness for the missing key or resorting to pliers to scratch them up in desperation. Small ribbed bolts may have been a better choice, but perhaps they were avoided for cable snag potential. I didn't even realise the allen key was there until I read the manual and found it hidden under the bottom handle.

- Black Mounts, Eggshell White OTA's .. it's a design faux pas that I can excuse but my wife thinks looks silly. She kinda liked the All-white observatory with White Edge HD and White EQ6 I suppose colour could have a minor impact on equipment temperature but regardless, it would be cool to see some consistency across the product lines so they match.

Apart from those minor quibbles I'm very excited to see this very solid, modern mount in action. I'm not looking forward to using the hand controller as I'm used to my EQMOD setup and the Planewave software is not available until Feb. I will miss my plate solving mostly. Also I tend to remote control from inside the house so the hand controller is just an annoying reason to go outside for target selection and what-not. Still, all this should be resolved in time. Feel free to ask questions if you have any.

I've also posted this on CN which will have some follow up Q&A but won't cross post here. Check thread at http://www.cloudynights.com/topic/55...ron-cgx/page-6 if you like.

So Dylan do i take it you imported the CGX direct and not through Bintel? If so who did you purchase through and was it at the current $2199 USD retail price? How did you ship and what was the all up import price with GST? These are important consideration for others considering the CGX. If Bintel or Celestron in some way facilitated or provided 'consideration' in the transaction then this could be seen as a product placement piece. Nice mount none the less.

Oh I've been asking for it via Bintel since it was announced a few months back. I didn't get any favours, I just had to wait for the shipment and release date like others. My order was one of a few for Bintel I believe. If you're interested in a newly released product definitely ask them ahead of time, they'll back order it for you no worries. Contact Bintel to confirm RRP. I think it's around $3.5k but don't quote me.

I did get a discount on the RRP but that's because I'm their web dev, it's not brand payola. I thought the review was fairly explicit about my brand relationships and my criticisms of the mount If I was trying to push the product and vendor I would've included pricing and ordering info, I just wanted to share the details for this anticipated mount. Hope that's a bit clearer!

(TLDR If it sucks - I'll tell you!)

Thanks Dylan, i have been considering ordering one from Optcorp, and had discussed with Luke at Andrews about their availability through them. Hence my interest. I would prefer the head unit only for my observatory but Celestron will not split it, despite the tripod criticism on CN. I will follow your adventure. Clear skies.

Nice one Dylan look forward to hearing how you get along with it and seeing the results you have a very understanding wife if she lets you setup your mount in the living room

Thanks and yep.. real world tests next. Will share as soon as possible.

In the meantime, my unboxing and setup overview video is below. I love the switch position memory! No more losing alignment when swapping OTAs, rebalancing or losing power!

Ok I checked with them. They are $3299 and I believe they only have 2 left and the store just closed for Christmas. It's not online yet so basically it's whoever calls in their order first when they reopen. Hope this helps!

Given the price of an EQ6, that looks like a pretty good deal

Looks like a nice new mount Looks quite stiff and bulky, that's good. If it doesn't make that jazzy persistent tracking noise that the EQ6 does, that would be nice

Dylan i have emailed them last night of my interest in one, hope that insures a place in the queue and we will have a conversation when they reopen. In the mean time i will try to work out how to control it with Sky Safari and Wifi.

From accounts over the pond it works with EQmod using the Celestron driver.

I've also put an order in - if that pricing holds, it will be a bit of a change in pricing policy for Celestron! My CGEM looks to have carked it, so it's a good excuse to upgrade I guess

Ok I had a chance to give it a test run tonight. First light! If there can be such a thing.. for a mount.

I ran the 2 star alignment + 2 calibration stars + ASPA polar alignment once after roughing it in, then over again after it was polar aligned. This allowed me to do 2 minute unguided exposures at a fairly long focal length (1480mm) f6.3 ... GOTOs were 100% spot-on.

Best single unprocessed sub here : http://deography.com/tmp/2min-unguided.jpg

Rough stack and process of 7 x 2m subs attached. Stars a little drifty but nothing that wouldn't be guided out already if I was. I will continue to hypertune the alignment though before moving onto guiding and those results.

Not bad for a hand controller alignment though, a promising start.

Dylan do you know of any sources for the pier adaptor for the CGX? I see Celestron has released a pdf file drawing of the required adaptor, but it looks very different to the CGEM adaptor sold by Altair invthe UK. Without a pier adaptor i can't see a CGX in my future.
General question to all readers, if i supplied a drawing can anyone make a CGX adaptor?

No idea sorry. I think I will go down this rabbit hole soon. I do note however that Richard Berry's review for Celestron.com was done with a pier! "Second, I wanted to determine how well the CGX would serve as the principal attraction of my small roll-off-roof observatory. Since the base of the equatorial head is designed to drop over and bolt to a 6½-inch O.D. steel pipe, the CGX comes ready and willing to serve atop a permanent pier in an amateur’s backyard observatory"

Sounds straightforward?

It's night #2 and I hope to get guiding when the stars reveal themselves shortly. I must note that today I added a guidscope and solar scope to the load, rebalanced by removing clutches and realised I lacked enough counterweights, then removed solar scope and rebalanced again. Tonight I've switched the mount on, used "Last alignment" and have done literally nothing. Told it to slew to Venus and boom... it's not dead centre but it's by the inner crosshair circle.

What a luxury! I imagine it's best practice to run All star polar align again though for any fractional slacking.
